Final project videos


All the final projects finished up nicely, and we have video and code for all of them. So, in case you want to try them out, here is some information:

4 bit maze [Daniel Jenkins, Andrew Wagner]:

Mr. Jenkins and Mr. Wager implemented the Arduino four bit maze found here, and explain their project in this video.

d-pad/joystick controlled Etch-a-Sketch [Coston Rowe, Andrew Hicks, David Thompson]:

Mr. Rowe, Mr. Hicks, and Mr. Thompson used Parallax servo motors and a homemade joystick/d-pad to remotely draw on an etch-a-sketch. Their Arduino code is here, and they describe their work in this video.

Daft punk helmet [Jacob Moxley, Cameron Darling]:

Mr. Moxley and Mr. Darliny used an Arduino Uno and the LoLShield they assembled to create a Daft Punk-inspired helmet with scrolling messages. Their code was based on cibomahto’s LoLShield library, with some modifications to fix lower-case letter display and implement sprite-style graphics. They describe their work in this video.

RFID tunes [Ali Cortez, Max Peeples]:

Mr. Cortez and Mr. Peeples implemented a tune generator based on reading RFID cards that encode pitches, notes, rests, etc. Their code and all project details are here, and they describe their work in this video.

“Incredimen” pseudo-Theremin [David Gillespie, Derek Brazzell]

Finally, Mr. Gillespie and Mr. Brazzel made a pseudo-Theremin. The main differences from a traditional Theremin are the use of lower frequency oscillators (~80kHz) to make things easier, and using a op-amp simple summing circuit for multiplexing rather than a more complicated mixer. The use of lower frequencies does impact the sensitivity, but it still works great and sounds very, very weird. They describe their work in this video, which apparently they spent quite a bit of time on!

If you want more project details, you can contact me and I'll either tell you what I know or put you in touch with the students who did the project.
